NLAAF testing new shoe design on treadmill. Early results are stunning.

Shoes, shoes and more shoes.  NLAAF has produced a second shoe design that takes shoes to a whole new level.

Think about a shoe that eliminates tripping or stumbling. What about a shoe that eliminates knee and hip issues from walking and running? What about a shoe that gives your athletic career an extended or new life? What about a shoe that eliminates lower limb pain from sports that require a lot of stop and go? What about a shoe that could reduce ankle and knee injuries?

Guess what? NLAAF is currently testing that shoe.

NLAAF learned so much from its’ current shoe design that it has come up with a whole new shoe. Early treadmill testing, running at 7 mph in the new shoe design, resulted in a 20 percent reduction in average heart rate over standard running shoes. Just think of running at the same speed using 20 percent less energy!

What is needed today to improve athletic performance is not a lighter shoe, a more flexible shoe or a more motion control shoe, but a totally brand new shoe.

Once again NLAAF is leading the way in bringing you an innovative and effective training solution. To learn more contact us today!

Myths

Treadmills do not cause injuries.

This is my response to a post about treadmills causing injuries.

The problem is not the treadmill, the treadmill just exposes the flaws in your biomechanics sooner than ground running does, but sooner or later you will have the same issue on ground running. Would you at that point blame the ground?

1983 study “Treadmills are often used in research projects to simulate overground locomotion, assuming that locomotion is similar on a treadmill and overground. The purpose of this investigation was to determine whether a treadmill could be used to simulate overground locomotion. Twenty-two subjects ran on four different surfaces: overground and three treadmills that differed in size and power. The kinematics of the right leg and foot were studied using two high-speed Locam cameras (lateral and posterior view). The subjects ran in two different shoes at four different speeds (3.0-6.0 m.s-1). The differences in the kinematics between treadmill and overground running could be divided into systematic and subject dependent components. Subjects systematically planted their feet in a flatter position on the treadmill than overground. Most of the lower extremity kinematic variables, however, showed inconsistent trends for individual subjects, depending on the individual subject’s running style, running speed, and shoe/treadmill situation. The differences were substantial. It is not yet understood how the human locomotor system adapts to a particular treadmill running situation. However, it is concluded that individual assessment of running kinematics on a treadmill for shoe or shoe orthotic assessment may possibly lead to inadequate conclusions about overground running.

That is between 7 and 10.5 mph
After 10.5 mph which is about 5:50 mile pace things can change. How many everyday people run 5:50 mile pace which is a sub 18 min 5k.

1995 study, Selected variables were measured to examine differences in overground and treadmill running at sprinting speeds of maximal effort. Five college-varsity sprinters volunteered to run 100-yd sprints in both overground and treadmill running conditions. After a minimum of 10 training sessions on the treadmill, the subjects were filmed (75 fps) sprinting 100 yd and expired respiratory gases were collected during an 18-min recovery period. The oxygen debt of the overground condition, means = 47.86 ml X kg-1, was 36% greater than the treadmill running condition, means = 30.64 ml X kg-1. Regardless of individual running style, the major biomechanical differences between treadmill and overground running conditions occurred during the support phase and were observed in the supporting leg. During treadmill running, the leg of the supporting lower extremity was less erect at contact (means = 83.9 vs 88.3 deg) and moved through a greater range of motion (means = 60.6 vs 54.5 deg) with a faster overall angular velocity (means = 566.36 vs 478.07 deg X s-1). The thigh of the supporting lower extremity was more erect at contact (means = 67.1 vs 61.1 deg) and moved with a slower overall angular velocity (means = 435.14 vs 528.77 deg X s-1). Data suggest that the moving treadmill belt reduces the energy requirements of the runner by bringing the supporting leg back under the body during the support phase of running.

So here again a combination of things may cause issue with how you run on a treadmill versus the ground, but it is not the treadmill that alters your running mechanics. It could even be a subconscious issue, but most of all it is a lack of instructions on how to use a treadmill properly.
